MAX6037CAUK33-T

Overview

The MAX6037CAUK33-T is a fixed series voltage reference IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides a stable output voltage of 3.3 V with an initial accuracy of 0.5%. The device features a low temperature coefficient of 6 PPM/C, ensuring stability across varying thermal conditions. It operates within an input voltage range up to 6 V and supports a maximum shunt current of 5 mA. The component is housed in a compact SOT-23-5 surface-mount package and functions reliably within an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Provides a precise fixed 3.3 V output with high initial accuracy for sensitive analog circuits.
• Features ultra-low temperature drift characteristics to maintain stability across wide thermal variations.
• Integrates shutdown functionality to minimize power consumption during inactive periods.
• Utilizes a compact SOT-23-5 package suitable for space-constrained portable designs.

Applications

• Portable instrumentation requiring stable reference voltages
• Battery-powered measurement systems
• Data acquisition systems
• Sensor signal conditioning circuits

Procurement Notes

Verify the specific suffix designation carefully, as the MAX6037 family includes variants with different accuracies and temperature coefficients. Confirm that the requested part matches the required 0.5% initial accuracy and 6 PPM/C temperature coefficient specifications. Ensure the SOT-23-5 package type aligns with the PCB footprint design. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a fixed 3.3 V reference is needed with tight accuracy requirements in a small form factor. The low temperature coefficient makes it suitable for applications experiencing significant thermal fluctuations. Consider the 5 mA shunt current limit when designing the load circuitry to ensure the reference remains within its regulation range without exceeding maximum ratings.

Part Context

This part belongs to the MAX6037 series of micropower voltage references designed for battery-operated equipment. The series offers various output voltages and accuracy grades, all sharing a common pinout and shutdown feature. The CAUK33 variant specifically denotes the 3.3 V output with 0.5% initial accuracy, distinguishing it from other precision or adjustable versions within the same product line.

Replacement Considerations

Check for MAX6037BAUK33 for higher accuracy options or MAX6037DAUK33 for tighter tolerances. Verify pin compatibility and electrical parameters before substituting with other series references from Analog Devices or Maxim Integrated.
